Installation Flow
Reference information
Operation
When the delivered subrack has been equipped with boards in cabinet, you can skip the steps involving "Installing
Subrack" and "Installing Boards and Components".
NOTE
If boards have been installed on a PTN 7900-24 before delivery, do not remove any board or module (such as the fan
module) during transportation. To learn how to replace boards and modules after an installation is complete, see the
chapters "Installing the Subrack" and "Installing Boards and Components ".

ESD Protection
Always wear ESD gloves or an ESD wrist strap prior to contact with the equipment or before handling boards or IC chips
to prevent damage to sensitive components due to electrostatic discharge from the human body. Ensure that the ESD
wrist strap is properly grounded.
Pre-Installation Check
Ensure that the equipment room, cabinets, power supplies, ground cables, optical cables, and associated devices are
ready for installation. Start the installation according to the engineering design documents after confirming that all
conditions are met.
Bundling Cables
Binding intervals between cable ties or optical fiber binding straps inside the cabinet cannot exceed 250 mm. (Binding
intervals cannot exceed 200 mm for user cables.)
Binding intervals between cable ties for all cables and corrugated pipes outside the cabinet are determined based on the
distance between the two horizontal beams. If the cable trough does not contain any beams, the binding intervals
between cable ties cannot exceed 250 mm.
Safety Information
The equipment is heavy. To prevent human injuries or equipment damage, always use a lifting device to transport or
position the equipment. Use a pallet truck or heavy-duty flat-bed truck to transport the equipment on even ground, and
use a cargo lift to transport the equipment between different floors.
Always wear protective gloves when lifting or transporting a cabinet to prevent hand injuries or damage to the cabinet
surface. Operators must protect themselves first if the cabinet unexpectedly tilts or even turns over during delivery.
This document provides guidelines for quick hardware installation. It describes procedures for onsite installation,
but does not describe pre-delivery assembly.
Installation Precautions

Requirements and Precautions for Operating Boards
22
Always wear ESD gloves to operating a board to prevent damage to sensitive components.
Any vacant slot must be covered by a filler panel to
prevent foreign objects from entering the subrack or
system ventilation ducts. Foreign objects may
cause an NE failure.
Boards are fragile and vulnerable. When transporting or placing a board, exercise caution and ensure that
the board is packed in a dedicated box to protect the board against damage.
Boards must be packed with original packaging materials during transportation. If the original packaging
materials are lost, contact Huawei technical support personnel.
Hold the protection plate under the board with hands and handle with care.

Before installing a subrack into a cabinet, remove the front door and side panels of the cabinet. For details,
see the N63B Cabinet Installation Guide.
To prevent human injuries or damage to the subrack, at least four people are required during the installation:
one to hold the subrack, the other to install the subrack.
